AlphaFold Protein Structure Database

Precomputed AlphaFold structure predictions for most known proteins.

Google DeepMind and EMBL-EBI

What it does

Precomputed structure predictions. Input: a UniProt accession; output: the AlphaFold model with pLDDT/PAE - the fastest way to get a usable structure for a target with no crystal.

When to use it

Use to grab a target model instantly instead of folding it yourself. These are predictions with pLDDT confidence, not experimental structures, and low-pLDDT regions should not be treated as real conformations.
